GLASS-WORKING APPARATUS.

To all whom t may concern:

Be it known that 1, PETER WVEGHT, a citizen of the United States of America, and resident of Bellaire, county of Belmont, and State of Ohio, have invented certain new and useful In'iprovements in Glass-Working Apparatus, of which vthe following is a specification.

This invention re-lates broadly to glass working apparatus, and more specifically to a paste-inold and dipping apparatus therefor.

struction, arrangement of parts and combi-v nations of elements which will hereinafter be described, reference being had to the accompanying drawings, in which- Figure 1 is a top plan view of the invention, with a portion of the operators platform broken away;

Fig. 2 is a sectional elevation on line 2-2, Fig. 1;

. Fig. 3 is an enlarged side elevation of the mold elevating and lowering mechanism;

Fig. 4 is an enlarged section on line 4--4, rig. s; i

Fig. 5 is a side elevation of the mold opening and closing mechanism;

Fig. 6 is a top plan view of the same;

Fig. 7 is an enlarged top plan view of the bottom-piece and the support therefor;

Fig. 8 is a longitudinal section of the same;

Fig. 9 is an enlarged top plan view of the mold support or base, showing a modified form of bottom-piece; and- I Fig. 10 is an enlarged section on line 1o 1o, rig. 9.

Serial No. 227,105.

vated from the water contained byv saidv Patented Apr. 8, 1h19.,

tank is a hinged sectional glass-mold 3. y

Said mold is mounted upon a suitable tablelike mold base or support l which is carried by oppositely-disposed rack-bars 5 that are vertically movable for eilecting raising and lowering of the mold-support 4. Said rack-` bars are disposed in slidable relation to upright supporting standards 6 located within and at opposite sides of the tank, each thereof having a longitudinal tongue 7 of dove-tail form slidably received in a correspondingly shaped channel 8 provided in the adjacent standard. f

Disposed in mesh with the teeth of each rack-bar 5 is a gear segment 9 carried bya transverse shaft 10 mounted in bearings` carried by the tank. Also carried by said shaft 10 is a pinion segment 11 in mesh with the teeth of a vertical rack-bar 12 which has its upper end projected above the level of a f platform 13 upon which the operator stands, y said platform being suitably mounted, as

upon a supporting frame or brackets 14 superposed on the tank. A foot-pedal 15 is soy carried by the projecting upper end ofsaid f: rack-bar 12, as shown. Said rack-bar is carried by and has dove-tail sliding relation to an upright standard 16.

As is obvious, when the rack-bar 12 is forced downward by foot-pressure applied to the pedal 15, the shaft 10 is rotated rearward and, through the intermediate mecha-` nism described, the mold is elevated from its normal lowered position to the dotted line position indicated in Figs. 2 and 3. The weight of the mold and mold-carrying parts serves to return the parts to their normal position when the elevating force is withdrawn.

A lever 17 fixed on said shaft 10 at a suiti will suffice.

Carried by the 'mold base or support 4l: is

a rearwardly extending tail-piece iflwhieh` carries thereon in alincd relation to the mold two upright bearing members 20 and 21 in which a horizontal rod is slidably mounted. Said rod carries upon its front end a cross-bar 2? to which are pivota-lly connected the rear ends ot' two links 45 which have their front ends similarly connected to the iold sections and which are designed, when f of said parts, relatively slight foot pressure Q A incenso actuated to advance and retract by longitudinal shifting movement of said rod, to effeet closing and opening, respectively, of said mold sections. A spiral spring 2-l carried by said rod 22 has its front end resting against lug or member 20 and its oppor. site end seated aga-inst a ixed collar 25 carried by said rod, said spring serving to nor' mally maintain said rod retracted, holding the iuold open, as is` most clearly shown in Figs. 1 and 6.

Carried by the rear end of the rod 22 is an .anti-friction roller 26, and engageable with said roller for edecting a -forward, or advancing, movement of said rod against the resistance offered by said spring 24 is the 'upwardly and forwardly inclined surface 27a of a rod-shifting member 27 which is vertically movable upon' an upright post 28,

having its lower end seated upon the upper end ota spiral spring 29 located in einbracing relation to said post. An upright pushlrod 30 carried by said member 27 proje'ets above the level of the platform 13 and bears a foot-piece 31 whereby force may be applied for depressing said member against the tension of its supporting spring 29. As is apl parent, during the raising and lower-inc' roller 26 to advance the rod 22 to mold-A closing position, which position `is maintained only so long as the depressing pres-4 sure applied to said member 27 is not released.

Located at a suitable point within the t'ront end of the tank 1 is a post or like support 38 upon which is adji'istably` mounted one end of an arm-like bracket 32 having an open longitudinal slot 33 in its outer end. Said slot is adapted to receive therein in vertical position a sleeve-like bearing 3i in which is rotatably held the spindle of, a bottom piece 36 which may have formed in its top face any design or pattern, as the star 37.

shown in Fig. 7, which it may be desired to form in the bottom of tile article produced in the mold. Said arm 32 is so positioned on its support 38,- aiid the sleeve-bearing 34 is so positioned in the slot 33, thatl the bottonipiece 36 is supported at the appropriate height and in a centered or axial position with respect to the mold, as shwnin Fig. 1. Said bottom-piecc serves as a bottom for the N'lldwhen the latter occupies-its operative or blowing position, and, consequently,

will impart to the bottoms of the blown articles any figure or design carried on its upper face. In practice, after the blowing ofan article and before the mold is lowered, the operator releases the depressin pressure applied to the rod-shifting inem er 2,7 which immediately resumes its normal elevated p0- sition, permitting the rod 22 to retract and open the mold, whereupon the latter ma be lowered without hindrance from said 0ttom-piece. Since said bottom-'piece must be lubricated,1 it must be permanently maintained above the level ofthe Water in'tlie tank to preventl the removal of the lubricant. This is provided .for iii-the' construction 'de scribed in which the bottom piece is notlowered with the mold. f

The table or mold-base 4 has therein an appropriately located opening 46 and an open slot 39 leading outward from said opening, said opening land slot-, receiving theA bottoni-piece 36 and its supporting arm or ,bracket 32. respectively, as the mold is lele-- l vated and lowered with respect thereto. y

The supporting arm 32 and bottom-piece 36 may be dispensed with when plain bot* toms are to be. formed in the ware, in which ease the construction shown iirFi s. 9 and 10 ma)v be substituted therefor. T iis modified construction includes a circular shouldered disk -lO adapted to seat in the opening 46 ot the table, which opening is preferably also shouldered, as shown at 41. Said'disk has therein a radial ,slot 42 through which may be ntroduoedtoa centered position the vertical stem 130i a bottom plate 44 Whereon the bottoms of the articles molded are formed.
